my 2month baby won't wake up night for feeds.if I try to wake up and she won't accept feeds.her birth weight was 2.5 for 25days it was 3.5..for 50days it's only 4kg..how can I increase her appetite to gain weight.

A. hello baby gaining a minimum of six hundred grams to 800 grams per month then it is a good weight gain and is absolutely nothing to worry about and anu concern then it is better to check with your doctor and if bm os not sufficient then give infant formula milk stage 1 using a bpa free bottle like Babyhug
